Abstract

Effective heating of the interior of the vehicle requires careful distribution of air. This applies especially to windscreening on glazed surfaces to ensure adequate visibility for the driver, especially in conditions of frost or dew settling. Here, research was carried out using a thermal imaging camera, with the help of which the thermal field was measured on the outer surface of a passenger car windscreen. Periodic tests of the thermal field on the outer surface of the glass allow for a quick diagnosis of possible defects by comparing the pattern from the new car with the tested one. In order to determine the amount of heat removed through the partition, a numerical scheme was proposed to solve the inverse and ill conditioned problem. The result of calculations are the values of heat flux density and heat transfer coefficient along a selected line.
